Specification of Letters Patent.

Patented Jan. 19, 1915.

To all whom it may concern: Be it known that I, LYNN W. MAcoMsnn. of Battle Creek in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Baling-Presses; and I hereby declare that the following is -a full, clear, andexact description thereof, reference being had to the ,.ccompanyin drawings, which form part ,1 of this speci cation.

This invention is a novel baler. or machine for compressing light, bulky materials such as rags and waste paper mto bales.

The invention particularly resides in the novel means for operating the presser-head to compress the material; novel means for releasing the presser-head at the end of a compressing operation; and novel means for raisin the presser-head.

It also urther provides novel features of construction and arrangement of parts of the baler which will be hereinafter clearly described with reference to the machine shown in the accompanying drawings,

which illustrate a baler em 0 ymg a practical and the at present preferred, form of the invention.

In said drawings:-Fi'gure 1 is a perspective view of the baler with the follower r presser-head, raised, and the upper door open, ready for filling. Fig. 2 is an enlarged erspective view of the presser-head, some of the parts connected therewith being shown detached. Fig. 3 1s a perspective view of the baler opened, showing a cornpressed bale therein. Fig. 4 is a detail new of the presser-head and its operating de vices detached. Fig. 5 is an enlarged top lan view of the baler, partly in section.

igs. 6 and 7 are enlarged top plan views of the presser-head operating devices. F1g.

8 is a vertical section on line 8-8, Fig. 6. Fig. 9 is a similar section in the line of one of the lugs. Fig. 10 is a perspective view of the presser-hen and its operating devices detached.

The baler comprises a body or baling chamber consisting of opposite side walls 1, and a rear wall 1, mounted upon a base v. frame 1", which base tpreferably projects beyond the front side 0 the baleras shown at 1. The sides and rear of the baler may be braced by flanged metal bars l as shown.

The baling chamber is open at top, and its front wall is formed by a large lower door 2, and a small upper door 2". These doors may be hinged to the front of one of the side walls 1 in any suitable manner. As shown they are hinged by means of a vertical rod 2" which engages perforated lugs 2 on the door 2 and similar lugs 2 on the door 2, and also extends through openings in the forward ends of the braces 1 attached to the adjacent side wall 1 of the chamber. The door 2 may be stiffened by transverse braces 2 and the door 2 by a top piece 2 and bottom flange 2. The door 2 preferably has a vertical flange or plate 2 on its front edge which is adapted to lap over the front edge of the adjacent side wall 1 when thedoor is closed so as to prevent lateral 1 spreading of the walls of the chamber when a bale is being compressed. The door 2 may be fastened in closed position by means of a latch 2" of any suitable kind. The upper door 2 may be secured, when closed, by a similar latch, or as shown it may have a lug 2 on its front edge engaging a notch 2" in the upper end of the flange 2 as shown. The invention however is not restricted to any particular construction of the baling chamber, but I preferably make the walls and doors of the baling chamber out of sheet steel, and stiffen them where necessary with angle and strap irons.

v making the parts as shown of metal I pro uce a very strong serviceable balim machine, that is easily handled and move and which occupies little space.

The upper ends of the side walls 1 of the chamber extend above the top edges of the door 2and back wall 1*, and are rigidly connected by transverse parallel bars 1. Attached to one of the bars 1 are upright bars 3 which extend above the bar 1 and are rigidly braced and secured in position by inclined braces 3, 3", the lower ends of braces 3 are fastened to the side walls 1, and the lower ends of braces 3 are fastened to the bars 1 as indicated in the drawings. The bars 3 serve to guide the presser-head actuating bars 4 in their vertical movements. These presser bars 4 are preferably formed of angle iron and .are connected at their lower ends to atransversely; dis

posed horizontal metal latei and' their upper ends are .connecte by a member or casting 4% Thepresser-head 5. is movably attached to the. re'sse'r-bars beneath plated as hereinafter escribed.

The side flanges of the resser-bars 4 lie against the faces of the bars 3 and are confinedin guideways formed by platesB? attached to the opposite sides ofplates 3 but spaced apart t ereby, see Fig. 5 slightly more thanthe thickness of the an es of resser-bars 4" as shown. The mem er or casting 4 attached to the'upper end of resser-bars, P'is provided with outwardly and upwardly curved lugs or horns 4",,4, which are adapted to be engaged respectively by 'ull bars 6, 6; said pull bars being prefera ly flat metalbars eachprovided with a longitudinal series of perforations 6, any one of which is adapted to engage the adjacent lug 4, l. The bars 6, (5* are pivotally connected at their lower ends to a lever 6, which'lies between thebar's 1 and is pivoted on abolt 6 transfixin' said bars 1 and the lever. Preferably I orm'the lever (3 of two parallel ,siinilar bars between which the lower ends of thebars 6', 6 are pivoted asshown in'Fig l, the pivotal connections of the bars 6, 6* to the lever 6 being at oin'ts e ui-distant from the ivot 6 of said. ever; he long arm of sai lever ar y extend throu h a slot 1 in the upper end of one of the 'si e membersl, as shown, and'is pivotally connected to the upper end of a rod 6 the lower end of which is in turn pivotally connected to a lever 6 that is pivoted atone end to the frame, at as 6'. Said lever 6 c'an'be manually operated. The bars 6B6? stand parallel with the presser-bars 4 at are separatedtherefrom by the member 4 andoneof the bars as shown. a

When the, lever 6 is oscillated the bars (i, 6* will be moved eppositely, and alternately raisedand' lowere As the pull bar 6, gar 6") is raised, it will ride over the lug 4' 'or 4'), but when said bar is lowered; it will engage its corresponding lug 4 (or 4) and pa 1 down the member 4;" and the parts"connected therewith thus depressing the resser-head 5. (ee Figs. 8 and 9).

It will be seen that when pull bar 6, or 6", rises, it will ride off and over the lug 4', (or 4) but will engage same on its descent. In order to insure the en agcment of the bar '6 or'G" with therelated ug 4, or 4, when it is desired to operate the Presser-head, and to disengage same therefromwhen it is desired toelevate the Presser-head rapidly; I attach to the member 4 a plate 4 which late is slit or notched to accommodate the are 0,

6*, see Figs. 6 and 7, and to guide the latter in their vertical movements. To the undcr side of this plate 4 are attached springs 6,

6, which are shown as fiat springs, but may be of other construction, and are respectively-adlrpted to engage pull bars (3, (5 and hold the latter yielding in engagement with thedu s 4, 4f,,and press, said bars yieldingly towar member 4". It will be seen that the said springs will allow pullibars 6, 6, to

- ride off and over the ln s t, 4 in the upward. movements of san bars, and on the downward-..movemcnts thereof will press them inward and cause them to engage the lilgSelbf'd and thus apply positive downward movement to the resser-bars 4. and there through to the prcsser-head. Thus when level 6 is operated the bars 6, (3, are alternately raised and lowered, and the bar that descends (say 6) engages with its related lug on the member 4a and forcibly depresses the latter, thereby depressing bars 4.

and the presser-head connected therewith; while the other bar (say 6) rises and rides over the lug on said member. With this construction I obtain a double acting prcsser mechanism, and the presser plate is continnail? depressed, on both the up' and down stro es of the lever 6, by the alternate action of the bars 6, 6". The slots in the plate 4 are sulliciently deep to allow the bars (5, 6" to automatically engage and disengage the lugs on the member 4 as described.

Vhen it i's de'sired to raise the prcsscrhead the bars 6, 6" should be both disengaged, and held disengaged, from the lugs 4, 4'; for this purpose a slide l is mounted on the plate 4: and adapted to move transversely of this plate between the bars 4 and the hers 6, 6; said slideinay be conveniently aided in sloop 4 attached to' the plate a.

he'slide P ha's its rear end turned down as at 4 to limit its forward movement by contact with the member 4*, see Fig. 7 A cam lever il'is 'jiv'oted to the forward end of this slide 4*. "0 the rear end of the slide is at tached a cross tend behind t Fi's. 6 an'dl y hen the cam lever 4 is turned into the position shown in Fig. 6 the slide is retracted and the s mags 6, 6 will yieldingly hold the bars 6 hf in engagement with the lugs 4, 4. If the cam lever be turned to the position shown in Fig. 7 the slide i will be drawn forward and the ilate l will engage the bars 6, 6 and move them away from and out of en a'gement with the lugs 4-, l, see

piece 4 the ends of which exie respective bars 6, (3*, see

, Fig. 7, and hold them in this position against the action of the springs (3, 6; this will permitjthe )r'ess'cr-bars 4;? to be raised or low ered in ependently of the bars (3, 6 and their operating devices.

The follower or presser-head 5 is preforably formed of metal, and comprises front and ifearf lates 5, 5" connected by a series i of paralle transverse bars 5. The front and rear pliites'niay be notched on their under sides as at 5 for a purpose hereinafter explained. This Presser-head is connected with or suspended from the lower ends of presser-bars P, see Fig. 2; and preferably I connect this presser-head slidably to said bars so that it can be slid backward or forward relatively to plate 4. For this pur pose I attach angle plates 4 to the lower end of the presser-bars P, adjacent the plate 4:, and to these angle plates are attached depending strap irons 4*, the lower ends of which are upturned to engage and support the adjacent bars 5 of the resser-head, see Fig. 2, and thus suspend the presser-head from the bars 4?, while permitting a horizontal sliding movement of the presser-head relative to plate at. This construction enables the presser-head, when in elevated position, to be pushed backward out of the way, as shown in Fig. 1, the presser-head then projecting partially out of the chamber through the opening above the top of the rear wall thereof as indicated in dotted lines in Fig. 5, thus permitting the baling chamher to be completely filled with material before the compressing operation.

As shown in Fig. 1 the waste paper or other material to be baled can be thrown into the baling chamber after the lower door 2 is closed, and when filled to the height of the door 2, the upper door 2 can be closed and the material thrown over the door into the chamber until the latter is completely filled; then the presser-head can be drawn forward, by hand, into operative position; and then be forcibly lowered by operating lever 6 as described.

When the bars 6, 6 are disengaged from the lugs, as shown in Fig. 7, the presser-head may be automatically raised, or its lifting be facilitated, by means of cables 7, which are attached to the ends of the plate 4, and wound upon drums 7 on a shaft 7 journaled in brackets 7 attached to one of the bars 1, or other fixed part.

The shaft 7 may be provided with suitable springs which will be tensioned when the Presser-head descends and will, when the presser-head is released, rotate the shaft to wind the cables and elevate the presser-head. As shown, a helical spring 7 is strung on the shaft 7", one end of said spring being attached to the shaft and the other end to one of the brackets 7, or other fixed point, so that the spring will be tensioned when the presser-head descends, and will cause the shaft to rotate and raise the presser-head when it is released, and will hold the presserhead in elevated position, as shown in Fig. 1.

The machine is preferably mounted upon short legs 1 at the corners of the base; and to the front legs are attached rollers or casters 1 in such manner that when it is desired to move the machine by simply tilting it forward its weight will be transferred from the legs to the rollers 1 and it can then be easily moved to any position desired; when restored to upright position the weight of the machine is supported on the legs 1 and the rollers 1 are raised slightly off the floor and relieved of strain.

The operation may be briefly summarized as follows: After the machine is moved to the desired point the bars 6, 6*, are disengaged from the lugs 4 4 by moving the cam-lever 4 into the position shown in Fig. 7, whereupon the presser-head 5 is raised by the action of the spring-controlled shaft 7 to the position shown in Fig. 1. Then the presser-head is slid backward so as to partly project out of the chamber and over the rear wall thereof, (as indicated in dotted lines Fig. 5). Then the door 2 is closed and the material to be compressed is thrown into the chamber until it reaches the top of the door 2; then the doorQ may be closed (or both doors could be closed) and the chamber completely filled with the material to be compressed. Then the presser-head is drawn forward and centrally positioned beneath the plate l; then lever i is turned to the position shown in Fig. 6 allowing bars 6, 6 to engage the lugs r, 4 Then lever G" is oscillated to cause the forcible descent of the Presser-head by the alternate pull of bars 6, 6 and the material is compressed to any desired extent. hen the material is sufiiciently compressed the doors 2, 2 may be opened and the hale tied in any desired manner and removed.

The notches 5 in the plates 5 enable ties to be placed around the bale while the presser-head is holding the bale compressed. The method of tying the bale does not form part of the present invention, but a convenient mode of tying the bale is as follows: Before closing door 2, the loop ends of ties W are engaged with hooks or lugs 10 on the front side of the machine base, and then led in and to the rear of the baling chamber and passed under a rod 101 which may be removably inserted and retained in holes 10 in the end walls 1, adjacent the rear bottom corners of the baling chamber; from thence the ties are carried up alongside the back wall of the chamber and out through openings 10 near the top of the back wall, to prevent the ties slipping or dropping out of place while the bale is being compressed. Art the commencement of the baling operation, or after the presser-head has partially descended, the door 2 may be opened and the ties slipped through the notches 5 between the presserhead and bale, and allowed to hang over the top of the door 2, or on top of the presserhead. lVhen the bale is compressed the door 2 is opened and the ends of the ties united, thus securely tying the bale. Then the presser-head is released and allowed to rise, and the bale is removed. These operations can be repeated indefinitely. The ties may be arranged or manipulated in any other desired manner so as to bind the compressed bale before it is discharged from the machine.
